Problems solved by technology

[0006] In view of the problems raised by the background technology, the purpose of the present invention is to propose a synthetic quartz stone preparation process imitating the three-dimensional texture of natural stone. The pattern texture of the prepared synthetic quartz stone has a strong sense of three-dimensionality, rich colors, and a texture comparable to natural stone texture. It has the advantages of corrosion resistance, high strength, flatness, not easy to deform, and no delamination, which solves the problems of poor texture, poor strength and corrosion resistance of existing synthetic quartz stones

preparation example Construction

[0054] (1) In the existing preparation process of synthetic quartz stone, the adhesive used is unsaturated polyester resin, and styrene is added as diluent and crosslinking agent in the existing unsaturated polyester resin. On the one hand, styrene will volatilize into the production workshop during the production process, which is not conducive to the health of employees; on the other hand, styrene and the iron filings mixed in the quartz ore during the crushing process will have a miscible reaction, and the gray-black color will affect the whiteness of the board surface. In order to improve the whiteness of the board surface, titanium dioxide needs to be added. The shading effect of titanium dioxide affects the transparency of the surface layer, making it difficult for the surface layer to present an ideal three-dimensional texture effect. The fabric of the present invention adopts epoxy resin without styrene, which reduces the volatilization of styrene in the production work...

[0115] A preparation process of synthetic quartz stone imitating the three-dimensional texture of natural stone, comprising the following steps:

[0116] a1. Pattern texture scanning: Send the natural stone slab to a high-resolution scanner, scan the texture on the surface of the natural stone slab and form a graphic file;

[0117] a2. male mold making: the graphics file is input into the engraving machine (the depth of the natural stone pattern texture color in the graphics file corresponds to the depth of the engraved knife), and engraving is carried out on the male mold material (being specifically an aluminum alloy plate) to obtain a material with For a three-dimensional concave-convex textured male mold, the surface of the male mold is coated with a release agent (specifically polyvinyl alcohol solution);

[0118] a3. Master mold making: On a flat and clean platform, use a level to check and adjust the platform feet until it is completely level. The male mold is placed o...

Abstract

The invention discloses a synthetic quartz stone preparation process imitating the three-dimensional texture of natural stone, comprising the following steps: a. Mold making: scanning the surface texture of the natural stone plate and forming a graphic file; Concave-convex texture male mold and female mold; b. base material preparation: stir the base material raw materials evenly, the raw material components of the base material include resin, and the resin is unsaturated polyester resin; c. base material pressing: put The base material is evenly spread on the master mold, and scraped, and vibrated and pressed after vacuuming. According to the synthetic quartz stone preparation process imitating the three-dimensional texture of natural stone, the pattern texture of the prepared synthetic quartz stone has a strong sense of three-dimensionality, rich colors, and a texture comparable to natural stone texture, and has corrosion resistance, high strength, smoothness, no deformation, and no peeling off. The advantage of the layer is to solve the problems of poor texture, poor strength and corrosion resistance of the existing synthetic quartz stone.

Description

technical field [0001] The invention relates to the technical field of quartz stone production, in particular to a preparation process of synthetic quartz stone imitating the three-dimensional texture of natural stone. Background technique [0002] Synthetic quartz stone is a kind of synthetic stone. It is made of quartz particles or a certain amount of glass particles as aggregate, with quartz powder as filler and unsaturated polyester resin as binder. After vacuuming, vibration compaction, The synthetic stone processed by curing and other steps has a hard texture and a dense structure, and has characteristics such as wear resistance, pressure resistance, high temperature resistance, corrosion resistance, and penetration resistance that other decorative materials cannot match. Quartz stone is widely used in public buildings such as hotels, restaurants and banks, as well as home decoration such as kitchen countertops, washstands and kitchen and bathroom walls. [0003] Natu...
